I am using a Roku Express +. I have an update issue. I am using version 9.3 and trying to update to 9.4. it downloads but when it tries to restart it drops connection. When I reboot and check it has't updated. I am only having issues with Sling.com. do you think the issues is with Roku player or with Sling?
Failure to update the system firmware has nothing to do with any particular channel/app. The only suggestion I have is to make sure you're using the supplied power adapter and not your TV's USB port. If you're already doing that then I don't have any other ideas.
